"installed an EV outlet. Very prompt to reply to initial request and was able to schedule within a few days. Very professional and tidy work, would certainly use them again. Price seemed more or less typical for a 220v outlet install as far as I can tell."

"Ray was instrumental in upgrading the electrical in my townhome, including installing new recessed lights, light fixtures, replacing receptacles with new ones and modern cover plates. He also relocated and installed a new subpanel providing dedicated circuits to appliances and the newly installed recessed lights. Ray is incredibly knowledgeable and very easy to work with and I would recommend him and happily use his services again."

"I am very happy I hired Aaron Murphy Electric for my EV charger install. Aaron did the work himself. He showed up exactly when he said he would. His workmanship was excellent. The Install looks extremely professional on the outside and was done safely in the inside. His price was more than fair. He knows what he is doing and didn't take any short cuts and left the area cleaner then it was when he got there. I am really happy."

"We submitted a service request through our AHS home warranty and were assigned to Budget Electric. It was after work hours. It affected our fridge and stove, so AHS put it as expedite/emergency. The next morning we were contacted by BE, and they found us a canceled appointment time for the following morning. In the meantime, I searched BE for reviews and saw quite a few negative reviews, leaving me nervous for our appointment. Based on the service we received, I don't know how they have bad reviews. The women answering my phone calls were very understanding and patient with may many phone calls. Michelle and another woman handled all my questions and concerns. There were a couple of times I wasn't able to reach them, but I'm assuming they were handling other calls or were at a unch break. Although it was an hour outside of our service window, we had an electrician show up soon after. With the storms, I think they're busy and sometimes run a little behind. Michael was the best and completely blew away all concerns as soon as he arrived. He was courteous and positive the entire time. He asked permission for coming inside, opening doors, going into rooms, etc. He patiently explained everything he did. He wasn't annoyed by curiosity or my questions. He was thorough and had diagnosed our problem in less than 5 minutes. Although it ended up being an issue for PG&E to fix, Michael double-checked the circuit breaker and boxes. He replaced a faulty fuse box to ensure no additional issues. After our service was complete, I shared our initial concerns based on previous reviews. Michael was still positive and genuinely courteous. He had positive things to say about Miguel and Abraham as well. He explained they have a high volume of service calls. He didn't make excuses. Without dismissing the other reviews, he said that with the volume of calls they do, there are probably some negative reviews. Although I don't typically leave reviews, I felt it was only fair to give an honest review after reading the negative reviews. Thanks to BE and Michael for service above and beyond!"

"Bill with Precision Remodeling was great to work with, very pleasant and informative, willing to answer all questions and concerns, and stayed on top of the project from start to finish. He and his team did a great job at an extremely competitive price. I would and have recommended Precision Remodeling to friends and family, and they have had similar experiences and good quality installations without issues. For context, my project was a new solar panel installation, higher amp electrical panel installation, and electric car charging outlets. The job was done perfectly."

FAQs for electrical for home addition or remodel installation projects in San Mateo, CA

Because installing coax outlets involves working around existing electrical wiring and confirming proper grounding, many homeowners prefer to hire a licensed electrician. A professional completes the work safely, secures the line behind the wall, and ensures the installation meets local code, which reduces the risk of damage or future repairs.

You still need a coaxial outlet for most cable-based internet services. The modem draws its signal from a cable line that terminates at a dedicated wall jack. Once the modem is online, your Wi-Fi router can broadcast the signal throughout the home, so the outlet’s location doesn’t affect wireless performance. If an existing jack is damaged or in an inconvenient spot, an electrician can move it or install a new one to maintain a strong, reliable connection.

Coaxial cable loses signal strength the farther it runs. A 50-foot length introduces noticeable loss, and a 100-foot stretch can drop the signal by roughly 30%. A weaker signal can result in a fuzzy picture or slower internet speeds. To maintain high performance, limit cable length whenever possible, select the correct cable grade, and route it efficiently. If your layout demands an exceptionally long run, an electrician can install an inline amplifier to boost the signal and maintain picture or data quality.
